From Formula 3 to AI Accountants: Ariel Harmoko, Co-Founder & CEO @ Artifact

Ariel Harmoko is the Co Founder and CEO of Artifact AI. Ariel joined James and Hector for a conversation that moves from race tracks to reconciliation engines.Ariel grew up in Jakarta, was thrown into Go Karts at eight, and went on to race professionally all the way to Formula 3 alongside the likes of Lando Norris and George Russell. That early immersion in high performance teams, engineering and discipline shaped how he now operates as a founder.He shares how a love of maths and science took him to boarding school in the UK, then into machine learning research at Cambridge while still a teenager, working on early diagnosis in medtech and later deploying internal GPT tools at JP Morgan.Today Ariel is building Artifact AI, an “agent accountant” that sits on top of existing ledgers like Xero, QuickBooks and NetSuite. The product tackles two huge problems for accounting firms. Fragmented legacy stacks and chronic staff shortages. Ariel explains how their agents ingest data, reconcile, post to ledgers and learn from human review, and why accuracy, auditability and trust are non negotiable in this space.The conversation covers selling into one of the most conservative industries on earth, founder led FDE style implementations, why advisory is the real margin in accounting, and how vertical AI and agentic workflows could reshape professional services.
